MILK-COOLER.

SIECIFICATION forming part of Letters Patent No. 478,482, dated July 5, 1892.

Application filed September '7, 1891. Serial No. 404,933. (No model.)

To @ZZ whom t may concern: Y

Be it known that I, SAMUEL W'. TOBEY, of Fairfield, in the county of Clay and State of Nebraska, have invented a new and Improved Milk-Cooler, of which the following is a full,

clear, and exact description.

My invention relates to improvements in milk-coolers, such as are adapted to hold milk when set for cream; and the object of lny inro vention is to produce a convenient cooler in which the milk may be easily inserted and removed, which Will serve to cool the milk from the bottom toward the top, thus insuring the rapid rise of cream, and which is constructed r 5 in such a Way that the cream cannot be con taminated.

To this end my invention consists in certain features ofV construction and combinations of parts, which will be hereinafter dezo scribed and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

z5 Figure lis a perspective view of the cooler. Fig. 2 is an enlarged longitudinal section of the same on the line 2 2 in Fig. 3, and Fig. 3 is a vertical cross-section on the line 3 3 in Fig. 2.

The cooler is provided with an exterior box 10, forming the cooler-frame, and this has a swinging cover ll,which enables the interior to be easily reached. The box has also an opening l2 in one side and within the box is 3 5 another smaller box 13, arranged so that there will be an air-space between it and the outer box, and this box has also an opening 12 opposite the opening 12 in the outer box. The top portions of the inner box are secured to crossstrips 14, which strengthen the inner box and form a support for the Water-tank, and the air-space between the two boxes is closed at the top by the strips l5, which strips also serve as a guide for the removable cover 16 of the inner box and tank, which cover has crossend strips 17, in which are hand-holes;13,\vhich facilitate the removal of the cover.

Vithin the inner box 13 is a water-tank 19, which is preferably made of sheet metal--such as galvanized iron-and this tank is held in 5o place by means of top flanges, which rest upon the strips 14. The tank 'has also along the top sides inclined flanges 19?, which cause any Water precipitatedon the cover 16 to draln off into the tank. The tank 19 is adapted 5 5 to contain the cans of milk, as indicated by dotted lines in Fig. 2, and in one end of the tank is av T-pipe 20, the horizontal portion 2l of which extends transversely across the tank and is provided with a series of holes, so that 6o the water may be delivered to the tank throughout its entire width, and the vertical portion 22 of the pipe terminates at its upper end in an outward bend 23, which projects through the Walls of the cooler, and is provided at its outer end with a funnel 24, in which the Water is poured to iill the tank. v At the opposite end of the tank are outlet-pipes 25 and 26, the pipe 25 being arranged near the bottoni and the pipe 26 near the top, and the pipe 7o 25 is kept closed except when the water is to be withdrawn from 'the tank, but the pipe 26 is left open and serves as an overiiow-pipe.

In practice the outside cover 11 is raised and the inner cover 16 removed and then 75 the milk-cans are placed in the tank 19, the covers are replaced, and suficient Water to fill the tank is poured into the funnel 24., and, if convenient, running water may be allowed to pass through the tank. The cool water as it 8o enters the tank will strike the bottoms of the cans, thus cooling the bottom portion of the milk first, so as to insure a rapid rise of cream, and the Warmer water will flow otf through the pipe 26.

It will be noticedthat provision is made for a free circulation of air around the tank and that there is no chance for any impure air to come in contact with the milk or cream.

Having thus fully described my invention, 9o I claim as new and desire to secure by Letters Patent-e 1. A milk-cooler comprisinga double-walled box having suitable covers,- a tank arranged centrally within the box, an inlet-,pipe having its inner end arranged transversely in the tank-bottom and provided with a series of holes and its outer end provided With a funnel, an outlet-pipe adjacent to the tank-botinside of the tank at the bottom thereof, and tom,and an overow-pi pe adjacent to the tankdischarge and overflow pipes leading from the ro top, substantially as described. tank out through the boxes, substantially as 2. A milk-cooler consisting of an inner and herein shown and described.
